We experienced 3 cases of fixed type cutaneous sporotrichosis confined to the face. Case 1 was a 32-month old child, affected over the nose. Case 2 was a 25-year old man, affected over the left cheek. Case 3 was a 71-year old man, affected over the nose. Histopathologically, chronic granulomatous inflammation with pseudoepitheliomatous hyperplasia was observed. Mycologically, typical dark brown to black colored colonines with moist, wrinkled and membranous surfaces were cultured. All patients were completely cured by oral administration of saturated KI and itraconazole combined therapy in a short period(40-90 days).

Objective Mood instability (MI) is a clinically significant trait associated with psychiatric disorders. However, there are no concise measurements to evaluate MI. The initial Mood Instability Questionnaire-Trait (MIQ-T) was developed to fill this gap. The current study aimed to create a short form of MIQ-T (MIQ-T-SF) that measures MI with high validity and reliability in the Korean general population.Methods Of the 59 items in the MIQ-T, 17 items were chosen for the MIQ-T-SF following the factor analysis process. In total, 540 participants completed the MIQ-T-SF. Cronbach’s alpha and McDonald’s omega were used to evaluate reliability. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to determine construct validity. Concurrent validity was confirmed via comparisons with Personality Assessment Inventory-Borderline Features Scale. Measurement invariance across gender and age groups was confirmed before analyzing differences in scores using Kruskal-Wallis test.Results The MIQ-T-SF displayed expected correlations and high internal consistency (α=0.71–0.90, Ωt=0.72–0.92). Using EFA and CFA, a five-factor structure was confirmed. Measurement invariance was supported, and gender differences were observed.Conclusion The MIQ-T-SF is an accurate and reliable method to detect MI in the Korean general population. The study’s results offer new perspectives for future studies on MI.

Purpose: Nutrition status is an important factor for perioperative morbidity in cancer surgery. The aim of this study was to evaluate the impact of the malnutrition risk, determined by Seoul National University Hospital-nutrition screening index (SNUH-NSI), on operative morbidity after colorectal surgery for cancer. Methods: This study enrolled 2,462 patients who had undergone colectomy for initially diagnosed colorectal cancer at Seoul National University Hospital from January 2011 to December 2014. We collected general patient information, SNUH-NSI and prognostic nutritional index (PNI) at administration and related parameters (serum albumin, cholesterol, total lymphocyte counts, hemoglobin and body mass index), operative method, hospital stay and operative morbidity. Results: Patients’ mean age was 62.12 years, and 423 patients (17.18%) were rated as severe malnutrition risk. Patients with high risk of malnutrition by SNUH-NSI or PNI, men, higher American Society of Anesthesiologists (ASA) class, palliative operation, and higher stage showed higher operative morbidity (P<0.05). On multivariate analysis, significant independent risk factors for operative morbidity were severe malnutrition by SNUH-NSI (odds ratio [OR], 1.868; 95% confidence interval [CI], 1.429–2.442; P<0.001) or PNI (OR, 1.596; 95% CI, 1.258–2.025; P<0.001), men (OR, 1.483; 95% CI, 1.174–1.876; P=0.001), or high ASA class (OR, 1.782; 95% CI, 1.136–2.795; P=0.012). Conclusion: Overall nutritional status, rather than single data, shows significant association with postoperative morbidity in patients who underwent colectomy. Especially severe malnutrition determined by SNUH-NSI, is an independent risk factor for perioperative morbidity. Nutritional support to severely malnourished patient by SNUH-NSI is expected to be effective in preventing complications after colectomy of colorectal carcinoma patients.

Purpose: Early diagnosis and management of therapeutic interventions are very important in chest trauma. Conventional chest X-rays (CXR) and computed tomography (CT) are the diagnostic tools that can be quickly implemented for chest trauma patients in the emergency department. In this study, the usefulness of the CT as a diagnostic measurement was examined by analyzing the ability to detect thoracic injuries in trauma patients who had visited the emergency department and undergone CXR and CT. Methods: This study involved 84 patients who had visited the emergency department due to chest trauma and who had undergone both CXR and CT during their diagnostic process. The patients` characteristics and early vital signs were examined through a retrospective analysis of their medical records, and the CXR and the CT saved in the Picture Archiving Communication System (PACS) were examined by a radiologist and an emergency physician to verify whether or not a lesion was present. Results: Pneumothoraxes, hemothoraxes, pneumomediastina, pulmonary lacerations, rib fractures, vertebral fractures, chest wall contusions, and subcutaneous emphysema were prevalently found in a statistically meaningful way (p<0.05) on the CT. Even though their statistical significance couldn`t be verified, other disorders, including aortic injury, were more prevalently found by CT than by CXR. Conclusion: CT implemented for chest trauma patients visiting the emergency department allowed disorders that couldn`t be found on CXR to be verified, which helped us to could accurately evaluate patients.

골수성 육종(Myeloid sarcoma)은 골수 외를 침범하는 질환으로 급성 골수성 백혈병에서 발생하는 드문 종양이다. inv (16) 염색체 이상을 가진 골수성 육종은 대부분 복강 내에서, 특히 소화관을 침범하는 종괴의 형태로 나타나지만 본 증례에서는 복막의 침윤 및 복수의 형태로 나타나 1예가 있어 보고하는 바이다. Myeloid sarcoma is an extramedullary myeloid neoplasm that usually involves the skin, soft tissues, and lymph nodes. Myeloid sarcoma is found in 2.5-9.1% of acute myeloid leukemia patients, usually those with t (8,21), while inv (16) is rarely associated with myeloid sarcoma. Consequently, little is known of the characteristics and incidence of inv (16) in myeloid sarcoma. Myeloid sarcoma in acute myeloid leukemia patients with inv (16) is most often found in the abdominal lesions, the intestinal tract is involved most commonly, in the form of a mass. Here, we report an unusual myeloid sarcoma presenting as peritoneal carcinomatosis in acute myeloid leukemia with inv (16) that appeared to be ascites. (Korean J Med 2015,89:581-584)

Purpose: Rectovaginal fistula can result from various causes and diverse surgical procedures have developed as a result. We investigated the outcomes of surgical treatments for rectovaginal fistula according to causes and procedures. Methods: Between 1998 and 2016, 92 patients underwent 128 operations for rectovaginal fistula. Prospectively collected data were recorded, and a retrospective review was conducted. Results: The median age was 49 years, and low fistula occurred in 58 patients (63.0%). The most common cause was radiation therapy, followed by pelvic operation, birth injury, perineal operation, cancer invasion, and trauma. The most common procedure during the first operation was diverting ostomy alone, followed by transanal rectal advancement flap, sphincteroplasty with perineoplasty, bowel resection, fistulectomy with seton placement, and Martius flap. Thirtyone patients (33.7%) experienced successful closure after the first operation. Repeated operations were performed in 16 patients (17.4%), including gracilis muscle transpositions, stem cell injections, and Martius flaps. The overall success rate was 42.4% (n = 39). Radiation therapy and pelvic operation as cause of fistula were significantly poor prognostic factors (P = 0.010, P = 0.045) and Crohn disease had a tendency for poor prognostic factors (P = 0.058). Conclusion: Radiation therapy and pelvic operation for cancer were more common causes than birth injury, and these causes of rectovaginal fistula were the most important prognostic factors. An individualized approach and repeated surgeries with complex or newly developed procedures, even among high-risk causes of fistula, may be necessary to achieve successful closure.

Proliferating trichilemmal tumor occurs predominantly over the scalp of women in the form of a single nodular lesion. Occasionally, the lesion appears in individuals with multiple trichilemmal cysts or shows involvement of a good portion of scalp with exophytic lesion or with a large plaque exhibiting surface nodularities. Histologically, the lesion is made up of proliferation of the outer root sheath epithelium with many central areas of trichilemmal keratinization and homogenous keratin cyst formation. The presence of low grade cellular atypia, individual cell keratinization, occasional dyskeratotic cells and mitotic figures may provide a false impression of an invasive squamous cell carcinoma. We are reporting a case of proliferating trichilemmal tumor in an 74-year-old woman with recent history of rapid enlagemnt of long shading exophytic scalptleision. Histologic section shows trichilemmal keratinization characterisic of a proliferating trichilemmal tumor. There were also abnormal mitosis, marked cellular plemorphism, and infiltrating margin suggesting malignant transformation.
